Contaminated soil poses a significant challenge for environmental remediation, impacting not only ecosystems but also land usability. At GN Solids America, we pride ourselves on being at the forefront of innovative solutions for contaminated soil washing. Our state-of-the-art equipment is designed to effectively reduce contaminated soil, reclaim clean soil, and minimize both the volume and treatment costs associated with contaminated materials.
Our specialized Contaminated Soil Flushing/Washing System utilizes a combination of physical and chemical methods to separate heavy metals and pollutants from the soil. This versatile solution effectively addresses various contaminants, including heavy metals, semi-volatile, and non-volatile organic pollutants. Whether in rivers, factories, or lakes, our systems can be tailored as either centralized stations or skid-mounted packages, ensuring adaptability to diverse working environments.
How Our Soil Washing Process Works
The soil washing procedure comprises several key steps, each essential for thorough cleaning and reclamation:
1. Crush & Screening: The process begins with crushing the contaminated soil, aided by a crushing bucket or crusher. Larger items such as rubber and plastic waste are separated using a rotary drum screen.
2. Soil Washing: The crushed soil is then transported to the washing machine, where water is used to create a solid-liquid mixture, initiating the washing reaction.
3. Coarse Screening: Following initial washing, the material undergoes coarse screening to separate larger particles, which can often be repurposed as construction fill.
4. Washing and Fine Screening: The slurry produced from coarse screening is processed through fine screening, further cleaning the materials and enabling them to be utilized as sustainable construction waste.
5. Cyclone Desanding: Fine sand (50-500 microns) is then separated using a cyclone desanding unit, producing sand suitable for building purposes.
6. Washing Reaction: Next, the liquid progresses to a washing reaction tank where specialized washing agents work to ionize heavy metals, facilitating separation from soil particles.
7. Mud-Water Separation: Utilizing our advanced VFD decanter centrifuge, the slurry is effectively separated into solid and liquid components. The separated mud is tested for reuse, while water undergoes additional treatment.
8. Chemical Dosing & Final Treatment: The aqueous solution is treated with chemicals to neutralize heavy metal ions, followed by flocculation to ensure thorough separation. Subsequent processing via filter presses or screw presses achieves dryness and readiness for safe disposal.
At GN Solids America, we see the transformation of contaminated soil as not just a technical challenge but an opportunity for innovation and sustainability. Our integrated contaminated soil washing systems not only provide effective remediation solutions but also promote the recycling and repurposing of materials, bringing us closer to a cleaner, healthier environment. Whether you’re dealing with heavy metals or oil-contaminated soils, our expert systems are designed to meet your needs and lead the way in responsible soil management.
